What is the Celtic word for south?

There isn't a single, universally accepted Celtic word for "south". This is because the Celtic languages are a family of languages, not a single language, and different branches have different words.

Here are some examples:

* Irish: deisceart (pronounced "desh-kert")

* Scottish Gaelic: deas

* Manx: jiass

* Welsh: deheu (pronounced "day-hoo")

* Breton: su

It's important to note that these are just a few examples, and other Celtic languages have their own words for south.
